Discovers New Mineralized Zone at the
Machichie Main Gold Deposit, Cuiú Cuiú Gold
District, Brazil
Vancouver, British Columbia--(Newsfile Corp. - March 26, 2025) -
Cabral Gold Inc. (TSXV: CBR)
(OTC Pink: CBGZF)
("Cabral" or the
"
Company
") is pleased to announce results from eleven
additional reverse circulation ("RC") drill holes and two trenches at the Machichie Main gold deposit
within the Cuiú Cuiú Gold District, Brazil.
Highlights
Drill hole RC0515 returned
10m @ 2.2 g/t gold from surface
and
3m @ 15.9 g/t gold
from 16m
depth within weathered gold-in-oxide material (saprolite). The hole also intersected
11m @ 0.9 g/t
gold
in fresh rock from 31m depth
Drill hole RC0504 drilled at the Machichie Main gold deposit at Cuiú Cuiú returned
12m @ 3.1 g/t
gold
including
3m @ 11.2 g/t gold
in weathered gold-in-oxide material at surface
The drill result from RC504 indicates the presence of a new previously unrecognized mineralized
zone located 40m north of the main mineralized structure at Machichie Main. The new zone is open
to the east and west and will require further drilling
Additional drill results from Machichie Main include
7m @ 2.8 g/t gold including 2m @ 7.5 g/t
gold
in RC502, and
15m @ 1.5 g/t gold
in RC506. Other notable results included
6m @ 0.9 g/t
gold
from RC508,
5m @ 1.2 g/t gold
from RC511, and
2m @ 6.6 g/t gold
from RC519
Trench CT054 also returned
13m @ 2.3 g/t gold
in saprolite material on surface including
5m @
5.8 g/t gold
Alan Carter, Cabral's President and CEO commented
, "The identification of a new and previously
unrecognised parallel zone of mineralization at Machichie Main is a very positive development.
Together with the other new drill and trench results released today, this underlines the potential of the
Machichie Main deposit to make a meaningful contribution to the near-term development plans for
the gold-in-oxide material at Cuiú Cuiú, as well as the global resource base within the district The
trench results are again significant because they confirm the presence of excellent grades within gold-
in-oxide material at surface. This bodes very well for our efforts to upgrade the Inferred resources at
Machichie Main and significantly updating the PFS study released in October 2024."
Machichie Main Trench and Drill Results
The Machichie Main zone is an E-W trending zone of gold mineralization which is located 500 metres
("m") north of the MG gold deposit (Figure 1). As with the MG and Central gold deposits, the zone of
primary mineralization within intrusive rocks is overlain by an extensive weathered layer consisting of
near-surface sediments and underlying saprolite (weathered intrusive rock). Both types of material are
considered gold-in-oxide material. A preliminary Inferred resource estimate of 3.73 milliion tonnes ("Mt")
@ 0.5 grams per tonne ("g/t") gold was calculated for the gold-in oxide material only at Machichie Main
and was released in October 2024 (see press release dated October 21, 2024).
Figure 1 Map showing location of known gold-in-oxide blankets with resources; Central, MG, PDM and
Machichie Main. The recently identified Jerimum Cima gold-in-oxide blanket is also shown but as yet
has no resources. Machichie Main is located just 500m north of the MG gold deposit and 3.5km NW
of the MG gold deposit.
* Only Indicated resources at Central and MG were considered in the PFS released on 21st October
2024. The main exploration targets (yellow dots) and distribution of historic placer gold workings (pale
yellow outlines) are also shown.

The main objective of the current program is to upgrade a significant portion of the current Inferred
resources to Indicated status so they can be included in the mine plan for the heap-leach starter
operation. The current program of drilling and trenching is also aimed at shedding light on the underlying
primary mineralized zone in the intrusive rocks and collecting additional material for a series of
metallurgical column-leach tests.
Results have been received on two additional trenches which have been developed recently at
Machichie Main to obtain samples for metallurgical testing and further define mineralization in the oxide
zone. Results have previously been received on two trenches with trench CT051 returning
20m @ 3.6 g/t
gold
including
4m @ 15.7 g/t gold
in weathered gold-in-oxide saprolite material (see press release
dated March 13, 2025).
Results were received on Trench CT054, which was excavated 225m east of CT051, and returned
13m
@ 2.3 g/t gold
in saprolite material including
5m @ 5.8 g/t gold.
Mineralization is open to the north and
south.
A second trench was taken 25m to the east of CT054 on section 553180E and returned 10m @
0.31 g/t gold (Figure 2).
These trench results continue to confirm the presence of significant high-grade gold mineralization within
gold-in-oxide material at Machichie Main and bode well for the possible inclusion of additional Indicated
resources from Machichie Main into an updated mine plan for the heap leach starter operation at Cuiú
Cuiú.
Results were received on 11 RC drill holes (RC502, RC504 to RC509, RC511, RC513, RC515 and
RC519) at Machichie Main. All of the holes were again drilled on the margins of the gold-in-oxide zone to
determine the extent of the near-surface mineralization, and apart from one hole they all intersected
multiple zones of mineralization (Table 1, Figure 2).

Several of the holes cut significant intercepts within the gold-in-oxide material, e.g.
12m @ 3.1 g/t gold
from surface including
3m @ 11.2 g/t gold
in RC504,
3m @ 1.3 g/t gold
in RC508,
3m @ 1.0 g/t gold
in RC511,
10m @ 2.2 g/t gold and 3m @ 15.9 g/t gold
in RC515 and
3m @ 2.3 g/t gold
in RC519.
Excellent results were returned from the underlying primary intrusive material with
7m @ 2.8 g/t gold
including 2m @ 7.5 g/t gold
in RC502 and
15m @ 1.5 g/t gold
in RC506. Other notable results
included
6m @ 0.9 g/t gold
from RC508,
5m @ 1.2 g/t gold
from RC511,
11m @ 0.9 g/t gold
from
RC515 and
2m @ 6.6 g/t gold
in RC519.
Hole RC 515 was drilled on the same section at trench CT051 which recently returned
20m @ 3.6 g/t
gold
including
4m @ 15.7 g/t gold
in gold-in-oxide material (see press release dated March 13 2025).
The mineralized interval intersected in RC515 i.e.
10m @ 2.2 g/t gold
and
3m @ 15.9 g/t gold
from
16m depth, is almost certainly the same mineralized zone intersected in trench CT051 (Figures 2 and 3,
Table 1)
Figure 3. Cross-section through line 552956E at Machichie Main (see Figure 2 for map). Note hole
RC0515 which returned 10m @ 2.2 g/t gold and 3m @ 15.9 g/t gold and 11m @ 0.9 g/t gold

Hole RC504 is of particular significance as it was drilled on the extreme northern end of section
553060E where a previous diamond drill hole, DDH303, was drilled from the south and intersected the
main mineralized zone at depth returning
6.4m @ 11.6 g/t gold
(see press release dated August 25,
2022). RC504 however was drilled from the north and cut a previously unrecognized zone in saprolite
returning
12m @ 3.1 g/t gold
from surface including
3m @ 11.2 g/t gold
(Figures 2 and 4, Table 1).
This zone is interpreted to be a new mineralized structure located parallel to and 40-50m north of the
main mineralized zone at Machichie Main. The zone remains open to the east west and at depth and will
require further drilling.
Figure 4. Cross-section through line 553060E at Machichie Main (see Figure 2 for map). Note hole
RC0504 which returned intersected a previously unrecognized mineralized zone to the north of the
known mineralized zones and returned 12m @ 3.1 g/t gold and 3m @ 11.2 g/t gold
Terms: g/t = grams / tonne, m = metres, Au = gold
